So, what do you think about the Dell Adamo ultra-thin and light laptop? It looks really nice, but at $2k, it's hard to justify. Plus, a non-user replaceable battery? What's the purpose of an ultra-light mobile PC if you can't replace the battery when you run out of juice? That just doesn't make any sense to me and I think that the Apple MacBook Air has set a poor example.
I have had several Dell PCs and I even use one right now to run Mac OS X (x86 mod/hack running OS X 10.5.2). I also run Ubuntu and XP, so it's currently configured for triple-boot. I've been happy with Dell and I've recently purchased some from the Dell outlet for a small medical office practice. I think the Adamo has tremendous potential, but the lack of a removable battery is a deal breaker for me. I'l stick with my Lenovo Thinkpad X200 tablet and continue to use that until someone comes out with a battery that will last over 24 hrs.
